Objective To compare clinical prognosis between intermittent high-volume predilution on-line hemofiltration (HF) and standard intermittent hemodialysis (HD) in critically ill patients with acute kidney injury (AKI).Methods This was a prospective,randomized,controlled single-centre clinical study.The mortality and recovery rate of kidney function were compared in critically ill adult patients with AKI between HF group (using intermittent high-volume predilution on-line HF,50 cases) and HD group (standard intermittent HD,45 cases).The prognosis of 60 d was followed up,including 60-day all-cause mortality,in-hospital all-cause mortality and recovery of kidney function.Results There were no statistical differences in basic clinical characteristics between 2 groups (P ＞ 0.05).The results of 60-day' follow-up showed,the mortality in HF group was 68.0％ (34/50),and in HD group was 82.2％ (37/45).There was statistical difference (risk ratio 0.75,95％ CI 0.80-1.28,P =0.036).There were no statistical differences in the in-hospital mortality and recovery rate of kidney function (P ＞ 0.05).There was no statistical difference in complication rate between 2 groups (P＞ 0.05).Conclusion The mortality is significantly lower in critically ill patients with AKI treated with intermittent high-volume predilution on-line HF,compared those treated with standard intermittent HD.

Objective To compare the effect of two different dialysis modalities, hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) on insulin resistance in patients with adult end-stage renal disease (ESRD), and to identify the possible predictive factors for insulin resistance. Methods Fifteen non-diabetic patients with ESRD (ESRD group) were selected. Eight patients were treated with HD (HD group), and 7 patients were treated with CAPD (CAPD group). The insulin inhibition was examined by hyper insulin-euglycemic glucose clamp technique before and after dialysis treatment, and the glucose disposal rate (GDR) was used as an index of insulin sensitivity during the clamp technique. Meanwhile, 8 healthy controls were selected as control group. The biochemical parameters which might be associated with insulin resistance were determined by multiple linear regression. Results The GDR in control group was (9.93 ± 1.33) mg/(kg · min), in ESRD group was (6.44 ± 1.76) mg/(kg·min), and there was statistical difference (P<0.05). The GDR in HD group after treatment was increased from (6.53 ± 1.84) mg/(kg · min) to (9.74 ± 2.88) mg/(kg · min), and there was statistical difference (P<0.01). The GDR in CAPD group after treatment was increased from (6.35 ± 1.65) mg/(kg·min) to (8.18 ± 1.76) mg/(kg·min), and there was statistical difference (P<0.05). Multiple linear regression result showed that the levels of urea nitrogen, hematocrit and bicarbonate were significant predictive factors in insulin resistance (P<0.05). Conclusions CAPD and HD therapy can improve insulin resistance in adult patients with ESRD.

OBJECTIVE To investigate the effect of furanodiene(FDE),a diterpene derived from the medicinal plant Zedoary,on apoptosis of human gastric cancer MGC-803 cells induced in vitro. METHODS MGC-803 cells were treated with FDE 46.29~740.74μmol·L-1 for 24,48 and 72 h,and the cell viability was detected with MTT assay. Cell morphology was observed by light microscopy and Hoechst33342 staining. Flow cytometry was used to detect cell apoptotic rate and cell cycle. Rh123 staining and fluorescence probe DCFH-DA were employed to detect the changes in mitochondrial membrane potential (MMP) and reactive oxygen species(ROS). RESULTS MTT Results showed that FDE 46.29-740.74μmol · L-1 exhibited significantly higher cytotoxicity to gastric cancer MGC-803 cells. IC50 for MGC-803 of 24,48 and 72 h treatment was 347.91,257.41 and 101.01μmol·L-1,respectively. Treatment with FDE 92.58-370.32μmol·L-1 for 24 h also caused significant morphological changes in MGC-803 cells. AnnexinⅤ-FITC/PI double staining showed that the apoptotic rate increased after FDE 92.58-370.32μmol·L-1 treatment for 24 h(P<0.05). FDE enabled MGC-803 cell cycle arrest in S phase. DCFH-DA staining showed that FDE resulted in an increase in intracellular ROS levels(P<0.05) when PDE concentration was 370.37μmol·L-1(P<0.05). MMP decreased after FDE treatment when PDE concen?tration was 370.37μmol·L-1(P<0.05). CONCLUSION FDE Possesses potent tumor selected toxicity and can induce apoptosis of MGC-803 cells through cell cycle arresting,which is related to inhibition of DNA biosynthesis.

Objective To observe the effect of moxibustion on the blood lipid and hemorheology in senile patients with coronary heart disease (CHD) due to heart blood stagnation who underwent interventional treatment.Method A hundred senile CHD patients were randomized into a treatment group and a control group, 50 cases in each group. The control group was intervened by conventional medications, while the treatment group was additionally by thunder-fire moxibustion. The blood lipid and hemorheology were observed before the treatment and after 3 treatment courses.Result The blood lipid parameters (including CHO, TG, HDL-C and LDL-C) were changed significantly in the treatment group after the intervention (P<0.05). The CHO, TG, and LDL-C levels of the treatment group were significantly different from that of the control group (P<0.05). The hemorheology parameters (whole blood viscosities at a high-, middle-, and low-shear rate, and fibrinogen) were significantly changed in the treatment group after the intervention (P<0.05). The whole blood viscosities at a high-, middle-, and low-shear of the treatment group were markedly different from that of the control group (P<0.05).Conclusion Thunder-fire moxibustion can down-regulate the blood lipid and blood viscosity of CHD patients undergone interventional treatment, and thus improve myocardial ischemia.

Objective To evaluate the effect of dexmedetomidine on the activity of glycogen synthase kinase-3 beta (GSK-3β) during propofol-induced apoptosis in hippocampal nerve cells of newborn rats.Methods Sixty male 7-day-old Sprague-Dawley rats,weighing 10-15 g,were divided into 6 groups (n=10 each) using a random number table:normal saline group (group NS),fat emulsion group (group F),propofol group (group P) and different doses of dexmedetomindine groups (group D25,group D50 and group D75).Normal saline and fat emulsion 100 μl were injected intraperitoneally in group NS and group F,respectively.In group P,propofol 50 mg/kg was intraperitoneally injected,and an increment of propofol 50 mg/kg was added after righting reflex completely recovered,with the total amount of 100 mg/kg.In group D25,group D50 and group D75,dexmedetomidine 25,50 and 75 μg/kg were intraperitoneally injected,respectively,and 30 min later propofol 100 mg/kg was administered.At 2 h after emergence,the rats were sacrificed,their brains were removed for determination of apoptosis in hippocampal nerve cells (by TUNEL),and the hippocampi were isolated for detection of the expression of GSK-3β and phosphorylated GSK-3β (p-GSK-3β) by Western blot analysis.The apoptosis index (AI) and ratio of p-GSK-3β/GSK-3β were calculated.Results Compared with group NS,AI was significantly increased,the expression of p-GSK-3β was down-regulated,and the p-GSK-3β/GSK-3β ratio was decreased in P,D25,D50 and D75 groups (P＜0.05).Compared with group P,AI was significantly decreased,the expression of p-GSK-3β was up-regulated,and the p-GSK-3β/GSK-3β ratio was increased in D25,D50 and D75 groups (P＜0.05).Compared with group D25,AI was significantly decreased (P＜0.05),and no significant change was found in the expression of p-GSK-3β or ratio of p-GSK-3β/GSK-3β in D50 and D75 groups (P＞0.05).Compared with group D50,AI was significantly decreased (P＜0.05),and no significant change was found in the expression of p-GSK-3β or ratio of p-GSK-3β/GSK-3β in group D75 (P＞0.05).Conclusion The mechanism by which dexmedetomidine attenuates propofol-induced apoptosis in hippocampal nerve cells may be related to inhibition of GSK-3β activity in newborn rats.
